| 1. | Normally the shear velocity is about half of the compressional velocity .
一般地说横波速度大约是纵波速度的一半。 |
| 2. | Since sound waves are longitudinal, only one dimension need be considered to obtain the sound wave solution .
由于声波是纵波，所以为了得到其解，只需考虑一维就行了。 |
| 3. | Unfortunately the shock conditions for accompanying longitudinal waves cannot be inferred at the outset without having detailed information about the shear wave .
很可惜，对伴随的纵波，冲击波条件却不能从一开始就在没有剪切波的详尽知识的情况下推测得出。 |
| 4. | Inversion of fracture density and azimuth using p - wave seismic data
利用纵波资料反演裂缝发育密度和方向 |
| 5. | When waves of a certain intensity are detected , the alarms are set off
当一定强度的纵波被探测到时，警报就发出了。 |
| 6. | When waves of a certain intensity are detected , the alarms are set off
当一定强度的纵波被检测到，预警系统便启动。 |
| 7. | Recommended practice for ultrasonic pulse - echo straight - beam tesing by the contact method

| 8. | A small angle incidence longitudinal wave for sensitive evaluation of fatigue cracks
超声小角度纵波灵敏检测疲劳小裂纹 |
